Apps for Bicycle Directions

I'm curious is there something like OSM but for directions using public transit? Some public repository of bus and train times.

I don't cycle, but my preferred mapping app is Locus Map.

https://www.locusmap.eu/

It's packed with features, the track recording is solid, you can use a couple different online track providers or install brouter for offline routing, and the list of map tile providers is impressive. It seems to be targeted at Europe, but the US maps are excellent too. You can use OSM as a base layer (online, or pay ~$1 per state for their pre-rendered OSM tiles for use offline), or you can use the USGS national topo map tiles. You can also import your own.

We went on a trip to Micronesia a few years back and I used it to mark POIs and record our boat trips around the islands to show our friends when we got home. There were no available maps of the area in the app, but I was able to find some high-resolution scanned images of USGS topo maps for the islands we visited and was able to import them into the app as an offline base layer. Worked great.

I feel like this effort is more for people who commute/ride from point A to point B as you said; another way to put it is, it is more for people who are _not_ actively training. If/when I'm training with power I don't much care about mapping, I know the routes I will take, lots of times in a park and/or around a natural feature of some sort (like a lake). It's only when trying to discover a new route that I would even consider using something like this -- but honestly, not even then. I usually plan a new route ahead of time, and can even preload it into my cycling computer. And do some exploring as well. I just did this yesterday, as a matter of fact, and it's awesome. Again, this is not when you're trying to get to your job on time, where routing based on traffic is what's needed.

Note: some bike computers also have built-in mapping, something I find useful on my Garmin Edge 530 is the breadcrumb feature which allows me to explore new territory to my heart's content and not worry about getting lost as I can just turn around at any point and follow the breadcrumbs on the map.

Note 2: I don't even have my phone out, it's always in my under-seat bag. Cycling computers are great, battery lasts forever (well in excess of 10 hours of riding with the computer on), visible in all lighting conditions, show a plethora of data at the same time (I have 8 live metrics shown at once), and are mounted in such a way that if you fall they likely won't get damaged, because a) they're unlikely to take a direct hit, and b) aren't big & heavy like a $1k iPhone 11 Pro Max with lots of glass that can shatter.

There's also a huge variation in what roads cyclists consider acceptable.

For example, one of our local highways has a speed limit of 55mph and a shoulder that is maybe 10 feet wide with a rumble strip near the cars. Is that a good road for bicycles or not? I'm OK with it but some of my riding friends are not. A bike path can be perfect for a family yet dangerous for practicing time trials.

I've also been surprised at how narrow some of my favorite roads are for driving. Just about any road is great if it doesn't have traffic. So a good road at lunch time is no good during rush hour.

So maybe the ultimate bicycle router would a) Offer a bunch of preferences just like you see for cars, e.g. "avoid freeways", "avoid tolls". b) Flag roads as "avoid", e.g. that four lane road with no shoulder next to the sidewalk. c) Specify roads with gravel. (OSM data can have this; not sure about Google.)

> I wonder if Strava could create two heat maps based on what I imagine are the two big clusters on their user base: road bikes and casual commuter cyclists.

I want this really badly. Around me (North Germany) the cycling infrastructure is great for the casual commuter, but the quality of paths for road bikes varies dramatically - some bike paths are beautifully smooth and wide, whilst others are bumpy/gravelly and too narrow for safely overtaking slower riders. Distinguishing between them using Strava heatmaps or other mapping tools seems impossible until I actually go out and ride them. Alternatively, an app where I could simply mark myself the roads I have ridden and a quality indicator would be useful (maybe this exists?).
